T 0 all whom it may concern:

Be it known that I, ARTHUR NORRISON MARE, a subject of the King of Great Britain and Ireland, residing at Rangiora Thorner, near Leeds, in the county of York and Kingdom of England, have invented new and useful Improvements in Apparatus for Drying Fabrics or Fibrous Material, of which the following is a specification.

This invention has reference to improvements in machinery or apparatus employed for drying warps of yarn or other fibrous material or products which may, or may not, be arranged either in continuous lengths in the form of festoons or in hanks, or otherwise.

The apparatus is also applicable for drying woven or felted fabrics whether arranged. in continuous lengths in the form of loops or festoons, or otherwise.

The above mentioned yarn or woven fibrous or felted fabrics are hereinafter termed and included in the term material.

This apparatus or machine is intended to receive the moist material which has been folded or wound inany usual and ordinary way, to automatically arrange and pass it through the machine in separate hanks or loops, or in festoons formed out of one or more continuous lengths and while so arranged to maintain a regular movement or travel of it through the machine and to subject it there continually to the action of an abundant current of heated air, thereby providing a more effective, expeditious, and economical means of forming such festoons, and of drying material in that form than has been previously ob tained, requiring less space, time, and labor.

The mechanism for carrying this invention into practice is illustrated in the accompany ing drawings, in which Figure 1. is a transverse section of the feed end of a single machine looking in the direction of the travel of the material. Fig. 2. is an enlarged part sectional elevation of the mangle motion. Fig. 3. is a plan looking at the top of the rack mechanism arranged over the fan chamber, in which the rack is shown in its central and also in its extreme position, and also a part sectional plan of the drying chamber of a single machine. Fig. 4. a longitudinal section of a single machine through the fan chamber and with the folding apparatus shown in dotted lines. Fig. 4* is an enlarged part sectional elevation of the delivery end of the machine shown in Fig. 4. Fig. 5. an enlarged part longitudinal and sectional elevation of a double machine showing portions of the upper and lower and also of the feed and delivery ends of the drying chamber. Fig. 6. an enlarged part sectional plan of same. Fig. 7. is an enlarged part elevation of the feed end of the machine. Fig. 8. is a part sectional plan of the top of one of the fan chambers of a double machine and half of the drying space with bracket removed, also a half plan of drying space and a fan chamber with the cover removed. Fig. 9. an elevation of the feed end of a double machine with the greater portion of the boarding and also the lifting gear for the lower tier of poles removed. Figs. 10, 11 and 12, are fragmentary views, corresponding to Figs. 4, 8 and 9, respectively, and showing a slightly difl erent construction.

Like parts in all the views are marked with similar letters of reference,

The fan chambers, fans, heating apparatus, and the means for circulating the warm air through the drying chamber may be of a similar construction and operate in a similar manner to those described in my U. S. application, filed 20th July 1906, Serial No. 327,040. The said parts are therefore only briefly referred to in this specification and are marked with small letters of reference in order to distinguish them from the other parts of this invention used in combination therewith, which are marked with capital letters and with numerals.

The machine consists of rectangular framework closed at the'top and bottom, and made of any suitable material such as wood, or a combination of wood and iron; and it is preferablybut not necessarily soof three contiguous chambers or compartments all placed parallel to the movement of the material, which passes longitudinally through the middle or larger compartmentwhen three compartments are employedherein after referred to as the drying chambera.

The two lateral compartments, when such are employed, are alike intended to each accommodate a number of fans, say, three fans 0, d, e, mounted upon a shaft f carried in bearings g, and the heating apparatus or surface h. At Figs. 8 and 9 the fan 0 is shown mounted on a separate shaft f.

In the drawings hereto annexed at Figs. 1 to 4 inclusive, only one lateral chamber 1) is shown, and it communicates with the drying chamber a. The said lateral compartment is hereinafter referred to as the fan chamber b.

ber b. But at Figs. 5, 6, 8 and 9 two fan chambers are shown.

The drying chamber a, has openings at both ends for the admission and exit of the material, while the fan chamber b is practically but not absolutely closed at its ends.

In the partition 11 (which separates the drying chamber a from the fan chamber 5, are provided openings of equal depth extending from the floor upwards through which moist air is drawn by the fans, also other and simi lar openings is extending from the ceiling downwards through which the same air af ter passing over the heating apparatus or surface his blown by the fans again into the drying chamber a. Some of the air that is thus circulated repeatedly through the drying chamber a may escape through openings including those by which the material enters or leaves it, and one or more additional fans, such as the fan 0 in Fig. 8, may be used for the special purpose of exhausting the moist air from the drying chamber a. To re lace the air so escaping or being removed, in et openings a are provided, adjustable at pleasure as to area, say, for example, at the points where the driving bands of the fans pass through the outer partition of the fan cham- These last named openings may, if desired, be provided with sliding doors, I), as clearly shown in Figs. 10, 11 and 12, by means of which the area of the openings may be adjusted at pleasure.

Z, 'n, m, are air direction plates.

The floors 0, p, (Fig. 5) of boards with slits or intervals between them for distributing the air current equally over the material be ing dried are fixed across the drying chamber a. One of them may be arranged immediately above the line of openings near the floor, and the other, say, immediately below the line of openings near the ceiling. The space between these two distributing floors is hereinafter referred to as the drying space.

All the above described parts are similar in construction and operate in a similar manner to those described in the said prior specification.

At each end of each of the two floors 0, p, and at the ends of the drying chamber a are carried in suitable bearings a number of horizontal revolving shafts, namely, four through shafts in all, marked respectively S S and 25, 25. Each shaft is fitted with a number of sprocket wheels. The said wheels are respectively marked R, R, and

thus eight wheels employed.

1, 1. As shown at Figs. 1 and 5 they are arranged to work in pairs, there being The sprocket wheels R at the feed end of the machine are mounted loosely on the shaft S The said sprocket wheels are connected together by four horizontal endless chains marked S and l, which pass through the drying space a in the same direction close to its sides. Two of the chains S are thus near the top of the space and they pro el along with them a number of rods or po es T suitably supported at their ends upon angle iron paths U, U or races, fixed to the framework of the machine. The other two chains 1 are near the bottom of the drying space and they also propel a like number of rods or poles 2 in a like manner.

The material to be dried is automatically passed over each rod of the upper tiers of rods or poles T in succession, and alternating with them, under each of the rods or poles 2 in the lower tier. Loops or festoons 30 are thus formed by the action of the machine itselffrom a continuous length of material which during its working occupy or are distributed throughout the whole of the drying space. This forming of the material into loops or festoons is effected and continually maintained by an arrangement of which the leading feature is the employment of two pairs of additional vertical endless chains 12 and 13 arranged respectively one pair at the feed end and one pair at the rear or delivery end of the drying chamber a. The two pairs of sprocket wheels,marked 8 and 8 and 8 and 8 ,at the feed end, and thetwo pairs of sprocket wheels marked 16 and 16 and 17 and 17 a at the delivery end, and which are mounted upon seven shafts or spindles marked 9, 9, 9 9 at the feed end, 15 15 and 15 at the delivery end, are similar to and are placed near to the four pairs -of a ove mentioned horizontal chains S and 1. Two other short vertical endless chains 23,working over sprocket wheels 20, 21, mounted upon shafts l9 and m -provided at the feed end of the machine are also employed for assisting the passage of every rod or pole 2 while empty from the lower to the upper line of rods above mentioned. These last named short vertical chains 23 are actuated from the nearest revolving shaft of the lower horizontal chains, or from any other convenient source, say, by spur gear- 1ng. 1

On each of the endless chains used there are provided a suitable number of projections, marked respectively 31, 32, 33, 3 1, and 24:, for propelling the rods or poles along the path prescribed for them.

Suitable gearing, such as for example, say, the mangle gear or device, or other like or equivalent device, is employed for maintaining a succession or a continuous cycle of intermittent movements of the endless chains and therefore of the rods. The mangle device consists of an oblong rack B with teeth on its outer perimeter into which gears a pinion 0 driven from pulley A through shaft D, bevel pinion E, and bevel wheel F. The rack B during its movement is made to work sprocket wheels used for carrying the four I vertical feed chains marked 12.

upon rollers 36. The upper and the lower horizontal lines of rods are moved alternately and at equal and suitable intervals through a short distance, carrying forward with them the whole of the material being dried, by sliding the rods on which it is stretched. along suitable races or ledges fixed to the sides of the drying chamber.

Immediately after each alternate movement of the upper or the lower pairs of chains S and 1 with its line of rods T and 2, the gearing employed imparts, as will be presently more fully described, a comparatively rapid reciprocating movement to the two pairs of longer vertical chains 12 and 13 to the extent of about the full vertical distance between the two lines of rods.

In the series of movements required for the forming of the material to be dried into festoons, and for their travel through the machine, six pairs of endless pitch chains are employed, of Ewarts or other similar type, namely, one pair of horizontal chains for upper tier, marked S. One pair of horizontal chains for lower tier marked 1. One pair of One pair of vertical delivery chains marked .13. One pair of vertical shorter chains marked 10. One pair of drivers for feed chains marked 23. Two single chains from rack marked 4 and 4 Motive power for these movements is received from any convenient source by the pulley A and its rotary motion may be converted into the required series or cycles of intermittent movements by the employment of, say, mangle gear consisting of the endless oblong rack B with straight or curved sides, and pinion C driven from the pulley A through the shaft I), the bevel pinion E and the wheel F which is rigidly connected to the rack pinion (1 both revolving on the fixed stud G carried by the arched bracket H which is shown to stand across the top of the fan chamber I) about the middle of its length. Immediately below this bracket and parallel with it is a plate I having two vertical flanges across its upper face as far apart as the full width of the rack, so that any rotary motion of the pinion 0 when engaged in either end of the rack causes the plate I to slide in the channel J which is also fixed across the fan chamber, and having underneath it a T shaped lever K provided with an axis or fulcrum L at the point where its three arms meet, the longest of whichv is actuated by the pin M,--working in the slot M in the channel J,-fixed in it which passes through. the channel J and through the sliding plate I to which is thus given. a limited reciprocating motion corresponding to the pitch line width of the rack. One of the shorter arm's K of the lever K is connected by the rod N to the double lever O fitted with a pawl 0 retained in position by a flat or other spring O engaging in a ratchet Wheel P keyed on the shaft S (see Fig. 4") on which are fixed tWo sprocket wheels R at the delivery end of the chamber a. These carry and actuate the two endless chains S which propel the upper tier of rods .which are arranged across the drying chamber a to about its full widthfreely along between the angle iron races U and U The other shorter arm K of the T lever K is connected by the rod V, the bell crank lever W and the rod X to the double lever Y, fitted with a pawl Y retained in a position by a flat or other spring Y with its ratchet wheel Z. These in a like manner actuate the two endless chains 1 working over sprocket wheels 1 mounted upon shafts 25 which propel the lower tier of rods 2arranged across the drying chamber to about its full width freely along between the races 3.

In order to transmit the motion of the pinion O as it engages in the sides of the rack B, from each end of the rack B is led a pitch chain 4, 4*. One of them 4, engages the sprocket wheel 5, .Figs. 4 and 7, which is keyed on the shaft S at the feed end of the machine, and therefore actuates the two similar sprocket wheels 7 keyed on the same shaft close to but outside of the fan chamber. These drive two similar wheels 9 on two spindles 9 to which theyare respectively connected by short endless pitch chains 10, Figs. 4 and 9. As shown in Figs. 4 and 9 there are fixed on the same two spindles 9 as the said two driven wheels two other and similar sprocket wheels 8 and 8 inside the chamber (1. These carry and actuate the two feed chains 12 which are thus reciprocated from the feed end of the rack when it is propelled to and fro by the pinion C. The chain 4 led from the other and rear end of the rack engages the sprocket wheel 14. This is keyed on the same through shaft 15 as are also keyed the two sprocket Wheels 16, 16. On spindles 15, 15', are also mounted two sprocket wheels 17 and 1.7 The sprocket wheels 16, 16 17 and 17 carry and actuate the two delivery chains 13 which are thus reciprocated from the delivery end of the rack. The two chains 4 and 4 secured to the rack B are continued towards each other until their ends are a convenient distance apart Where they are connected by a suitable device for adjusting them as they wear so as to be taut enough to engage the two sprocket wheels 5 and 14 properly without loss of motion. As each of the rods in the lower return tier 2 below the chains 1 arrives in succession at the feed end of the machine, it is necessary that it should be effectually removed from the lower tier by being raised so far as to enable the feed chains 12 to lift it to the upper tier T of rods. This is effect-ed as follows: Across the feed end of the machine, below the lowermost tier of rods 2 a shaft 19 is provided on which are mounted two sprocket Wheels 20. Two similar wheels 21 are mounted directly above them and connected to the wheels 20 by two endless pitch chains of suitable length 23 on each of which at regular intervals are four projections or attachments 24 similar to those on the chains 1 and S, and in order that these attachments may work correctly with' the horizontal chains, the shaft 19 is driven from the shaft 25 at four times its own speed by means of the spur wheel 26 and the pinion 27. The pawls 28 move freely on the pivots 29 so as to allow the rods so lifted to pass upwards, after which the pawls fall immediately into their former position so as to guide properly the rods regularly returned by the feed chains from the upper to the lower tier. he effect of these successive cycles or movements is that there is obtained a cycle-of four successive movements in which the siX hereinbefore mentioned chains-five pairs of which carry polesare employed, whereby the se arate rods'are regularly and automatical y inserted between folds of the material at the top and also at the bottom of the drying space as it enters the machine so that every rod in succession takes its place in the upper and in the lower traveling line of rods, and these rods are also at the exit end of the machine as regularly and automatically re turned by the chains, though not necessarily by the same pair of chains, to be automatically reinserted at the feed end as before.

The material after being. dried may be delivered by the machine to either of its ends, and may be there folded or wound by it in any usual method, such as by cuttle on brackets 42.

In this apparatus wool may be also dried by forming the festoons of netting and placing the wool in one or more layers or pockets of the netting.

The material 30 is passed into the drying chamber a through openings 37 at the feed end of the machine and is threaded or passed,-

as shown in dotted lines at Fig. 5,over each of the lower row of rods T in the upper tier and under each of the upper row of rods 2 in the lower tier until the opening 38 at the delivery end of the machine is reached.

The upper. row of the upper tier of rods T and the lower row of the lower tier of rods-2 are termed free rods as they are returned unloaded.

To automatically insert the rods T and 2 within the folds or festoons of the material to be dried there are four successive movements of the endless chains S, 1, 12, 13, 23, as follows :Two of the rods 2 having been first received respectively by the chains 12 and 13 from the lower tier, namely, one at each end of the machine, as hereafter described, the upper endless chains S are then moved to the extent of the pitch of the rods T carrying forward the loaded lower row of drops at 39 into the delivery chains 13 by which it is conveyed down to the upper rowof the lower tier on chains 1. Simultaneously with this movement of the rods, the free rods T in the upper tier are moved and one of them is passed to the feed chains 12. The feed chains 12, and the delivery chains 13 all move together, the feed chains taking the rods just received from the returning chains of the upper tier down between the two folds of fresh moist material to and between the projections 32 on chains 1 of the upper row of loaded rods on the lower tier. The delivery chains take down to the upper row of the lower tier one of the rods T from the loaded and lower row of rods T in the upper tier so passing it from between the folds of dried material. A free rod at the delivery end of the same lower chains 1 is returned by them to the lower row thereof. The lower chains 1 on receiving the said two rods are moved a pitch of the rods, carrying forward the lower tier of loaded rods 2, one of which is lifted to the delivery chains 13 and returning to the same extent the row of free rods in the lower tier. One of the free rods 2.is car ried by a projection 24 on the endless chains 23 up to the feed chains 12. As this latter rod is carried up by the feed chains 12 it comes in contact with the underside of the moist material, and by the time the race U is reached the said materialwill have been made to surround-the upper surface of the rod. The feed chains 12 and the delivery chains 13 are then returned simultaneously to their former positions, as shown at Fig. 5; the feed chains 12 carrying with them the just mentioned free rod from the lower tier to form the now completed loop or festoon, and the delivery chains 13 carrying a rod from between the two folds of dried material to the upper chains S to be carried to and returned free by them on the upper level.

By the herein described means the upper row of the upper tier of rods T and the lower row of the lower tier of rods 2 are kept supplied with the correct number of rods for insertion between the loops or festoons of material to be dried.

In the herein described arrangement the material 30 is shown at Fig. 5 to be drawn into the machine at its feed 'end by the tension of the rods or poles on the material as they are placed in position in the horizontal races and within the top and bottom portions of the folds or festoons of the same. As the rods or poles upon the said upper and the lower races are intermittently and simul taneously traversed through the drying chamber, the material is thereby carried forwards so as to pass out at the delivery end. But when desired, the machine may be arranged for the material to be returned to the same end, as shown by dotted line 40.
